Description:

Project Proposal of AAC Production Line AAC PlantAnnual out put 50,000-300,000m3I Production Technique1. Product Principle1) Technology OrientationProduction and application of aerated concrete has a history more
than 40 years in China. Viewing from technology point, high quality
products can use 3mm special sand slurry technology to meet the
construction requests and 50% energy saving goals. (When mortar
joint is less than 3mm, take thermal conductivity coefficient of
wall as 1; when mortar joint is more than 3mm, take thermal
conductivity coefficient of wall as 1.5). Based on the history of
the aerated concrete development, only high quality products can
bring a prosperous market. Thus, the technology orientation of this
scheme is high-class products according to China Standard
GB11968-2006.2) Production CapacityThe product is aerated concrete block and the output is 150,000m3
per year. The first phase can be equipped according to 100,000m3
per year. There is a reservation of plate in consideration of
user's need.3) Product SpecificationProducts conform to requirement of 04~07 grade blocks stated in
GB11968-2006.General Specifications of Aerated Concrete Blocks

Quick Detail:

Following the domestic development requirement regarding energy
saving and environmental protection, we have upgraded, innovated
and developed series of AAC production line equipment based on
initiation from and absorption of the advanced German technology
and design concept. So far we have supplied all kinds of AAC
production line equipment in different facility configurations and
production capacities to domestic and abroad customers. In the
meanwhile, we have provided customers with various kinds of service
such as upgrade of equipment, expansion of production capacity,
analysis of raw material, systematic process design and layout,
complete project management, and so on.

Raw Material:Sand,Lime,Cement,Gypsum, Aluminum powder,Water

Power:380~450kw,220V,380V

We can supply different equipment configuration for following AAC
production lines:- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 50,000m3- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 100,000m3- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 150,000m3- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 200,000m3- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 250,000m3- AAC Block and Panel Production Line in Annual Output (Production
Capacity) of 300,000m3

1. Cement425 # cement shall be acceptable.

2. SandThe sand shall be requested as standard JC/T 622<sand for
silicate building products>, The more quartz content, the better
result of production.

Autoclaved Aerated Concrete AAC Production Line AAC Plant used for
products of AAC.

Operation Instruction:

One-shift production may be put into practice when piecework system
is carried out in the enterprise, but working hours must be
prolonged and workers of the shift must be increased, and also
labor protection should be done well. If four autoclaves are
arranged in Phase One, fixed persons are organized in one shift.

Fly-Ash: fly ash is waste from Thermal plant.Fly ash is rich in silica and
aluminum oxide ,so it is good raw material to make aac block. Fly
ash is also divided into two kinds--wet fly ash, dry fly ash.The
dealing way will vary as per the fly ash condition

Sand: Except fly ash,Sand can be the main material too.The requests is
that the Silica content is above 69% .Sea sand can not be used as
aac raw material.

Lime: Active powered lime is a requirement for giving the real aeration
to the product. In phase 1 we can aim to buy the active lime
directly. In phase -2 we can think of having backward integration
and making a lime powering unit at site to have a more competitive
advantage, We can also think of a lime burning klin inside the
factory premises. The project financials however have not
considered the costs of powering unit, and the lime kiln in this
project. Different qualities of lime are available, and depending
on the raw materials, the mix design can be chosen to get the
optimal quality of production.

OPC cement. This Project aims to utilize OPC cement as main binder material.
It will give faster strength to the bricks, besides giving improved
consistent quality. It also ensures a better cost effectiveness for
the same. Using OPC will be a standardized practice. The other
prime advantages of using OPC (compared to other binders) is it's
easy availability locally through nationwide Retail Network of
Cement Companies.

Gypsum: This too is an industrial waste. This is available as an
industrial byproduct of Fertilizer Plant. Gypsum is responsible to
give long term strength to the Blocks.

Aluminum Power. Finely ground Aluminum power is used in very limited quantity (
less than 0.5%), so that it reacts with active lime, and silica in
base material to make the aeration.
